To all whom t may concern:

Be it kn-ownthat I. Fi'mns'r IV. Born, a citizen of the United States, residing at Providence, in the county or' Providence and State ot' Rhode Island, have invented a new and useful Improvement in Automobile- Iiocks, of which the following is a specilication.

This invention relates to certain new and useful improvements in an automobile lock and especially to an improved lock for securel \Y holdingr the brakes of an automobile or other vehicle, applied or operative:

Theinvention consists in a lock to be applied tothe brake bands of vehicles. the keeper part being mounted on one end of the band and they locking bolt carried by the opposite-end ot' said band foi-'entering the keeper part when the brake is applied whore it is securely locked against releasement'of the band should the usual lna-ke-operating pedal or lever be released.

Further, the invention resides in the features of construction and arrangements and combinations of parts hereinafter described and claimed, reference being had to the accompanying drawing wherein Figure 1 is an elevation of a brake drum and the encircling band, ot' a Well known type of automobile brake.,` showing the present invention in its inoperative position, and

`Fig. 2 is a horizontal section on line--2--2 of Fig. l, the lock of the keeper being left in elevation, and the improved device disclosed in its operative position.

More particularly, the invention consists of a tubular Aor otherwise form' of keeper 1 and a locking bolt 2 which is received in the socketed or opened end of the keeper and 'provided in its free or received end with -a series of openings or not-ches A suitable lock.4 is carried by th keeper in a casing formed'or secured thereon, the` bolt 5 of said lock 4 entering the chamber of the keeper through the side wall thereof for en` gaging in one of the series` of openings 3. It desired, the `outer face of bolt 5 may be beveled. as at (i. and the forward end of the.

locking bolt Q tapered to permit of the latter riding past the bolt as the brake hand is tightened or'the ordinary square bol-t may he used in which case the lock is operated by a key after the brake has been set up.

The invention may be applied to many types of band brakes so it is not intended Specification of Letters Patent.

to limit its application to only that type illustrated in which 7 indicates the drum that is usually carried on the rear axle 8 and is encircled by the twopart brake band t). The band tightening lever is of bellcrank design and has pivotal mount-ing at 1t). the shorterarm 11 being pivotally connected in a direct manner to one end of the band while the longer arm l2 is connected through an adjusting link 13 with-the upstanding wall l-l which constitutes the opposite terminal of said band. v

The improved lock has its keeper part carried bv one end of the brake band and its lockingl bolt mounted on the opposite end ot.' the same. Suitable means for mounting the partsl may be employed although a pivotal mounting ot' the parts is here disclosed, the saine consisting in providing rearwardly extending ears l5 of the keeper part for re ceiviir'gr therebetween a forwardlyextending ear lli. on the upstanding end wall 14, said ears beingv pivotally joined through the intermediary of pin 1T. rl`he locking bolt is indirectly connected to the. opposite end of the brake band through the instrumentality ot the shorter arm Il of the band-tightening lever to which it is pivotally connected by pin 18.

In operation, under ordinary or running conditions the bolt of the lock is retracted, that. is to say withdrawn from the openings 8. lVhen in use the bolt' is released by a key and as the band is tightened by pulling on rod i9 the ends lof said band are drawn into closer relation with the resultant telescopic. action of the locking bolt in the The openings or notches 3 arelarranged so as to readily Vbe engaged by the holt 5 so that, when the brake has been applied` the band-will be retained in close cnr' brace with its drinn by the' band lock. To

release the brake. the operator inserts a key into the locker and actuates the same to withdraw the bolt vt'rom its engaged notch.

The lock is especially efticient in attempts at theft, as the bauds are securely held in tight embrace about their drums. `The improved device is disposed in an obscure and out-otthe-wn'vv7 place and may he applied to' the regular brake band Without appreciable added cost.

Having thus described my invention, what I claim' as new and desire to secure by Letters Patent is- 1. In an automobile lock, a drum, an en-l circling two-part band having opposing terminals one of which is provided with an upstantling end wall having a forwardly extendine ear, a bell-crank lever having,r one arm connected to the other terminal, means connecting the opposite terminal to the other :1x-1n ot the lever, a 'tubular keeper part having' rearwardly emendingr ears rceeiving.; the first ear and pivotally connected thereto, a locking bolt pivotally connected to the first arm of the lever and having its free einl receivable by the keeper part and provided with a series ot' openings, and a,

lock carried by the keeper part and provided with a bolt projecting' into the chamber of the keeper part for engaging in the series of openings of the loekngibolt for holding the band in its operative position.

2. A lock for automobiles having a brake drinn, an encircling band, and 'means for tightening the band about the' drum, said lock comprising' a keeper part carried by one end of the band, and a locking bolt connectet' to the opposite end of said band for engagement. with the keeper part when the band is tightened for holding the latter op' erat-ive` 3. A lock for vehicles having a drum` an encircling brake band therefor, and means for applying the band, said lock compris-- ing aY socketed keeper part carried by one end of the band, a locking bolt connected to the opposite end of the band for engaging in and being guided by the keeper when the band is tightened, and means carried by the keeper for holding the bolt therein to retain the brake band operative.

- 4. In combination with a brake band and its connected and operating bell-crank 1ever, of a lock for holding the band operative against actuation by the lever, said lock comprising a lock bolt and a keeper therefor, one lock part carried vby one end of the band and the cooperating lock part carried by the bell-crank lever for being moved thereby to an operative position When said lever is operated to apply the brake.

5. In an automobile look, a drum, an encircling brake band having Opposing terminals, a bell-crank lever having 'one arm con nectetlto one terminal, means connecting the opposite terminal to the other arm of the' 'leven a tubular keeper part pivotally connected to the-latter terminal, a locking bolt pivotally connected to the first ,arm of the lever and having' its free end receivable by the keeper part and provided with a series of openings, and a lock carried by the keeper part and provided With a bolt projecting into the chamber of the'keeper part for engaging in the series of openings of the locking bolt for holding the band in its operative position. f

In' testimony whereof I have signed'my name to this specification in the presence of two subscribing witnesses. Y
